1. First, you need to plan the network and determine the target location of cross-network landing storage. The target location can be a dedicated server or a storage device, such as a network storage device (NAS) or a hard disk array (RAID).

2. Ensure that the target location can be connected to the network segment where the monitoring system is located. This can be achieved by configuring network devices (such as switches and routers) to ensure smooth network communication between the monitoring system and the target location.

3. Set storage strategies, such as storage by time period, cyclic overwrite storage, etc. This can make rational use of storage space and ensure the continuity of monitoring data.

4. After the setting is completed, test and monitor to ensure that the monitoring data can be stored normally across network segments. Check the status of storage devices regularly to ensure their normal operation.
